Struct HeuristicClassifier 

pub struct HeuristicClassifier { /* private fields */ }

Fast classifier based entirely on language-agnostic structural signals.

No keyword matching. Works identically for English, Korean, Japanese, or any other language. Signals used:

Signal	What it measures
Message length	Longer = more complex request
Line count	Multi-line = structured request
Code blocks (```)	Code-related task
File paths	File operation task
Symbol density	Technical/code content
Question form (?)	Likely Q&A → lower tier
Single sentence	Simple → lower tier
Context tokens	Rich conversation → higher
Turn count	More turns → richer context

Produces a score in [0.0, 1.0]:

• ≤ 0.3 → simple Q&A, greeting, single-line → Low tier
• 0.3–0.7 → moderate → Medium tier
• ≥ 0.7 → complex, multi-file, code-heavy → High tier

Implementations

impl HeuristicClassifier

pub fn new() -> Self

Create with default thresholds.

pub fn classify(&self, input: &ClassifierInput) -> f64

Classify the input, returning a complexity score in [0.0, 1.0].
